I'm currently in a field stripped 50L GoLite Jam pack that weighs ~26 oz. My 3-season, western mountain, thru-hiking base pack weight is typically ~9 lbs, and I like to have the capacity to carry 5-6 days food + water. I'm not a Super UL hiker. I want the pack to be able to handle a Berikade Weekender when needed in the Sierras for JMT and PCT thrus. The pack should be able to carry a max load of ~20 lbs.
So folks, what UL backpacks do you recommend that could get my backpack down to the 14-18 oz range?
Thanks!
